Explain thigomotropism in detail
Answers
Answer:
The movement of plant due to the external stimulus is call thigotropism.
Answer:
Also referred to as haptotropism, thigmotropism is the movement or change in orientation of a plant’s growth as a reaction to touch. The orienting factor is generally a hard surface that can change the direction of the plant’s growth or the growth of one of its organs. Thigmotropism can be in the form of opening or closing of parts of the plant such as the petals or leaves, the coiling of the plant around the surface, as well as other ways. Thigmotropism can be used in ways that increase the chance of a plant catching light for photosynthesis.
Thigmotropism is one example of tropism, which is the responding of a plant to environmental stimuli by growing towards or away from them. In other words, the reaction can be positive or negative. For instance, a stem can grow upwards towards the sun, and roots can grow away from an object in the soil. Other forms of tropism include phototropism, which is a plant’s response to light.
